So, I've done an auto-upgrade on my backend system. It was previously running R5D1, and the upgrade appears to have gone through properly. All my recordings are intact, and scheduled recordings have continued to record. No hiccups that I've detected, all went well.....

I load up my backend IP in a browser, authenticate myself, and click the RRDTOOL link only to see a bunch of blank graphs. Nothing is filled in at all. The graphs are updating though, if I leave things sit for a while and then refresh the page the timeline does move along, just no data is populating.

The next thing I did was go into /var/lib/rrd and created a backup directory, and moved *.rrd into this directory (thought maybe the old .rrd files from when I had things working under R5D1 were present and somehow monkeying with the process. So I took them out of the equation, ran the /etc/cron.hourly/rrd_km script and it did succesfully re-create the .rrd files under /var/lib/rrd, it also recreated the png files (which I also deletd from /var/www/rrdtool/) but again I'm getting just blank graphs.

Should I have to do anything at all to get rrdtool working with r5e50? or is it completely built in and turned on straight out of the box? My frontend system is running R5E50 as well, and was reinstalled fresh (not an upgrade like my backend, but an auto-install) and is experiencing the same thing.

I've followed the posts here regarding RRD stuff and it seems that most people just seem to have it working, I don't see much discussion specific to R5350. I did follow the wiki directions when I was running R5D1 and had no troubles getting it online. There is a note on that page saying Please skip to the bottom for notes about RE50, but all I see when I scroll down is notes indicating that some graphs may be empty after a re-install of R5E50, but it doesn't go into any details as to why. I'm running HDA not SDA so I don't need to worry about any of those changes, and was running fine with mbmon rather than lmsensors previously, so again I don't see what I would need to edit regarding that.

Anyone have any thoughts?

I'm more than willing to fuss with my cronjobs to get this working if that is where the problem lies. I am thinking perhaps that this isn't my issue. The timestamp on my .png files is updating on it's own, so I do think that the cronjob is running my scripts. If I run the rrd_km file manually should I not see the graphs populating?

There are other issues covered in that thread involving permissions and ownership that need to be corrected.

In particular I remember that the /var/www/rrdtool*, /var/www/rrdtool/* and /var/lib/rrd/ (and contents) need to be checked. They should all belong to www-data:www-data and be world readable.

Hmmm... That link seems to be broken for some reason, wonder if it's an artifact of the forums problems tha occured over the weekend... :?

I'll dig up the link (the hard way) and give it a go, just wanted to make sure that what I thought I was seeing wasn't an indication of a different problem.


Thanks for the push in the right direction.

root@backend:/var/www/rrdtool#


This is perhaps where my problem is.....
Here's what I did to correct this

Code:
root@backend:/var/www/rrdtool# chown www-data.www-data *


Now I get www-data as owner when checking here again:

Code:
root@backend:/var/www/rrdtool# ls -al

Now to check the /var/lib/rrd/ directory...

Code:
root@backend:/var/lib/rrd# ls -al
total 708
drwxr-xr-x  3 root root   4096 Jan 23 18:50 .
drwxr-xr-x 35 root root   4096 Dec 20 10:54 ..
-rw-r--r--  1 root root  28640 Jan 23 22:05 ambtemp.rrd
-rw-r--r--  1 root root  84784 Jan 23 22:05 cpu.rrd
-rw-r--r--  1 root root  84784 Jan 23 18:17 cpu.rrd.bak
-rw-r--r--  1 root root  28640 Jan 23 22:05 cputemp.rrd
-rw-r--r--  1 root root  28640 Jan 23 18:17 cputemp.rrd.bak
-rw-r--r--  1 root root  56712 Jan 23 22:05 disk.rrd
-rw-r--r--  1 root root  56712 Jan 23 18:39 disk.rrd.bak
-rw-r--r--  1 root root  56712 Jan 23 22:05 eth0.rrd
-rw-r--r--  1 root root  28640 Jan 23 22:05 hda.rrd
-rw-r--r--  1 root root  28640 Jan 23 22:05 mbtemp.rrd
-rw-r--r--  1 root root 197072 Jan 23 22:05 mem.rrd


Same deal here, all owned by root.

To fix I did the same thing again....

Code:
root@backend:/var/lib/rrd# chown www-data.www-data *


Things look better here now....

Code:

root@backend:/var/lib/rrd# ls -al
total 708
drwxr-xr-x  3 www-data www-data   4096 Jan 23 18:50 .
drwxr-xr-x 35 root     root       4096 Dec 20 10:54 ..
-rw-r--r--  1 www-data www-data  28640 Jan 23 22:15 ambtemp.rrd
drwxr-xr-x  2 www-data www-data   4096 Jan 23 18:50 backup
-rw-r--r--  1 www-data www-data  84784 Jan 23 22:15 cpu.rrd
-rw-r--r--  1 www-data www-data  84784 Jan 23 18:17 cpu.rrd.bak
-rw-r--r--  1 www-data www-data  28640 Jan 23 22:15 cputemp.rrd
-rw-r--r--  1 www-data www-data  28640 Jan 23 18:17 cputemp.rrd.bak
-rw-r--r--  1 www-data www-data  56712 Jan 23 22:15 disk.rrd
-rw-r--r--  1 www-data www-data  56712 Jan 23 18:39 disk.rrd.bak
-rw-r--r--  1 www-data www-data  56712 Jan 23 22:15 eth0.rrd
-rw-r--r--  1 www-data www-data  28640 Jan 23 22:15 hda.rrd
-rw-r--r--  1 www-data www-data  28640 Jan 23 22:15 mbtemp.rrd
-rw-r--r--  1 www-data www-data 197072 Jan 23 22:15 mem.rrd


There, again the files have all been moved over to www-data, looking much better. Lets give www-data the actual rrd directory.

Code:
root@backend:/var/lib# chown www-data.www-data rrd/


There, now /var/lib/rrd/ is owned by www-data and so are all of it's innards.





TJC thanks muchly for the insight here, as I've typed/copied/pasted and wandered through these steps I've had two successful intervals update on my graphs. Everything appears to be on track.
